Abstract: Provided herein are a method for producing a hydrocarbon adsorption catalyst includes dealuminated zeolite by heat-treating a zeolite in moisture-containing air at a first temperature to remove a portion of aluminum included in the zeolite, and supporting a metal on a carrier including the zeolite after the heat-treating and a hydrocarbon adsorption catalyst prepared using the same method. The metal-supported support may be additionally heat-treated in moisture-containing air at a second temperature that is higher than the first temperature.

Abstract: The present disclosure relates to a refrigerator with an improved lighting structure. The refrigerator includes a main body in which a storage compartment is formed, a light source provided on an inner surface of the storage compartment to provide light, and a lighting cover provided to cover the light source, wherein the lighting cover includes a first opening formed to irradiate light in a direction perpendicular to the inner surface of the storage compartment, and a second opening formed to be inclined with respect to the inner surface so that light is irradiated to the front of the storage compartment.
